1.Which of the following elements is likely to have the highest concentration inside a human cell?
K
Cs
Na
Rb
Li

2.Which of the following has an amphoteric oxide?
Be
Ca
Sr
Ba

3.In the following list of metals, the strongest reducing agent is
Rb
Na
Cs
K
Li


i REALLY NEED HELP!!!

The only logical answers, I believe, for #1 are Na or K.

2. Here is a web site for amphoterism.
http://en.wikipedia.org/wiki/Amphoteric

3. All of these metals are in group IA of the periodic table. The reducing power increases as we move down the column from top to bottom.

Check that answer for #3. I believe the strongest reducing agent is Li.
